Thought she was on the mend yesterday - appetite returned and looking brighter.
This morning it was obviously the end of the road. I think the underlying problem was her gizzard not working properly, similar effect as a blocked crop but without any apparent blockage - been going on for a few months on and off but it ended up as peritonitis/salpingitis.

So sorry, Rick to hear about Aeriel.
I have wall-to-wall redmite at the moment, but only in one roosting hut, all the others are totally clear, but at least it is getting under control. A nasty problem but not as sad as yours. I've just bought a spray that goes into their fluffed bum feathers when their backs are turned so quite a problem to pick the time to do it. They have baldish heads, but seem otherwise healthy and bright and are still laying.

BYM, thanks.
On to "red stop" expensive for a lot of hens, but it does seem to work, now on day 7 (of 10), and cannot see any, just ratty headed hens in the big hut
they are growing tufty plumage back now, so all seems well.
Yes, she certainly was a lovely girl, Rick.
